Gearbox Mounts

The differential bushings secure the differential to the subframe. Over time, the rubber material naturally oxidizes, stretches, and deteriorates due to driving conditions and environmental exposure. As the bushings wear, the differential is allowed to shift, which can lead to clunking during acceleration, vibrations throughout the vehicle, and premature wear of the driveshaft and differential bearings.

Our Differential Bushing Kit provides all three rear differential bushings along with new mounting hardware, delivering a complete solution that restores your Cayenne’s performance, reliability, and safety.

Comprising the primary differential mounting bushes, the kit provides a controlled yet flexible connection between the rear differential housing and the vehicle structure. Manufactured from high-quality bonded rubber and metal components, these bushes are designed to absorb drivetrain loads and vibrations while maintaining precise differential alignment during acceleration, braking and cornering.  

What This Product Does:

• Secures the rear differential assembly to the chassis.
• Controls drivetrain and differential movement under load.
• Absorbs noise, vibration and harshness generated by the drivetrain.
• Maintains correct differential positioning and alignment.
• Reduces shock loads transferred through the vehicle structure.
• Improves ride comfort and driving refinement.
• Supports smooth and efficient power delivery to the wheels.
• Helps protect surrounding drivetrain and suspension components from excessive stress.

• Clunking or knocking noises from the rear of the vehicle.
• Excessive differential movement during acceleration or deceleration.
• Drivetrain shunt when engaging drive or changing gear.
• Increased vibration felt through the cabin or floorpan.
• Thumping noises during take-off or load changes.
• Reduced drivetrain refinement.
• Rear-end instability under acceleration.
• Visible cracking, splitting or separation of the rubber bush material.
• Premature wear of driveshafts, mounts or associated drivetrain components.

• Rear differential mounting bushes are subjected to constant torque loads, road impacts, vibration and environmental exposure. Over time, the rubber components can harden, crack, compress or separate from their metal housings, reducing their ability to absorb movement and vibration effectively.
• When the bushes deteriorate, the differential can move excessively within its mountings, creating unwanted noise, vibration and stress throughout the drivetrain. Left unchecked, this excessive movement can accelerate wear of driveshafts, mounting brackets, suspension components and the differential itself.
• Replacing worn differential mounting bushes restores proper drivetrain support, improves vehicle refinement and ensures precise differential alignment. A genuine Porsche bush kit provides factory-correct fitment, excellent vibration isolation and long-term durability, helping maintain the smooth performance, handling stability and driving comfort expected from your Porsche.

The mounting bushes act as a flexible connection between the rear differential housing and the chassis, controlling drivetrain movement while absorbing torque reactions generated during acceleration, braking and gear changes. Constructed from high-grade bonded rubber and metal components, these bushes are engineered to withstand substantial mechanical loads and harsh operating conditions while maintaining precise differential positioning.  

What This Product Does:

• Secures the rear differential assembly to the vehicle chassis.
• Controls differential movement under load.
• Absorbs drivetrain vibration and noise.
• Maintains correct drivetrain alignment.
• Reduces shock loads transferred through the chassis.
• Improves driving refinement and ride comfort.
• Supports smooth power delivery to the rear wheels.
• Protects surrounding drivetrain and suspension components from excessive stress.

• Clunking or knocking noises from the rear of the vehicle.
• Excessive differential movement during acceleration or deceleration.
• Drivetrain shunt or jolting during gear changes.
• Increased vibration felt through the vehicle.
• Thumping noises when engaging drive.
• Rear-end instability under heavy acceleration.
• Visible cracking, splitting or collapse of the rubber bushes.
• Uneven loading of drivetrain components.
• Premature wear of driveshafts, mounts or suspension components.

• Rear differential mounting bushes are subjected to constant torque loads, vibration, road impacts and environmental exposure throughout their service life. Over time, the rubber elements can harden, crack, compress or separate from their metal housings, reducing their ability to control differential movement effectively.
• Worn differential bushes can allow excessive movement of the rear differential assembly, resulting in unwanted noise, drivetrain vibration and reduced driving refinement. Continued operation with deteriorated mounts may place additional stress on the differential housing, driveshafts, mounting brackets and suspension components, potentially leading to more extensive repairs.
• Replacing worn rear differential mounting bushes restores proper drivetrain support, improves vehicle refinement and helps maintain precise power transfer to the rear wheels. An OE Match replacement kit provides factory-style fitment, reliable vibration isolation and long-term durability, ensuring your Porsche continues to deliver the smooth performance and driving dynamics it was engineered to provide.
